Reasons for the seasons

Guiding Question: How does the tilt of the earths axis affect affect the light it affects at it rotates around the sun?

When it comes to winter in the northern hemisphere, which areas get the most concentrated light? When it is winter in the norther hemisphere, it is summer in the southern, meaning that area has the best concentrated light. Areas near the equator are the brightest and warmest, and the south pole receives the least amount if light and is the coldest. On the other hand, in the northern hemisphere there is much less light. there is some near the equator and almost nothing in the north pole.

Compare your observations between the way the light hit the equator during winter and summer between the north pole and the equator In summer, the northern hemisphere is tilted slight towards the sun, therefore there is more light in the north pole and everywhere from the equator up. In the winter, the northern hemisphere is tilted slightly away from the sun, therefor there is less light. There is hardly any light in the north pole and not very much from the equator up.

If the squares become larger from the light on the grid, what can you infer about the heat of the light shining on it? If the size of the square gets larger, I can probably conclude that the heat bearing down on it is warmer. Because of the light shining on it, it will get warmer and the grids will grow bigger.

According to your observations, which areas on earth are warmest? which areas are coolest? I would say that the areas closest to the equator are the warmest because no matter what season it is, most of the concentrated light always shines in that spot. The coldest areas on this planet are probably the poles. Because even in summer, hardly any light reaches there to warm it up.

What time of year would the toothpicks shadow be longest? When would it be shortest? I would guess that the time of year when the shadow is longest would be summer because that's when the most light would be shining on it, and because light can't break through barriers, it causes a shadow. Which means that the time of year when the shadow would be shortest would be winter because little light is shining on it.

How are the amounts of heat and light received in a square related to the angle of the suns rays? The more concentrated the light from the sun is, the brighter and straighter the squares will appear on the earth. The angle of light will cause the squares to appear stretched or faint when it comes at it from a slight tilt.

Use information form your observations to write an explanation of why the seasons change
Because of Earth's orbit, the southern and northern hemisphere will alternately tilt towards or from the sun. The light and heat reflected from the sun is what causes the seasons. When the Northern Hemisphere is tilted towards the sun, it's either summer or spring, and when it's tilted away it's either fall or winter.
